摘　　要：[目的]研究蜡皮蜥繁殖特征。[方法]每月购买5~6只雄性蜡皮蜥成体,解剖其生殖器官,并进行形态和组织学特征观察。[结果]蜡皮蜥雄性生殖器官组织结构具有一定年周期变化。睾丸重量和曲细精管管径,每年6月达峰值后迅速下降,8月降至最小值,9月开始增大,冬眠期发育缓慢,出蛰后继续增大;附睾和输精管的管径及管壁厚的年周期变化与睾丸重的变化情况基本相同;生精活动随生殖器官的周期性变化也发生相应的年周期变化。[结论]利用精巢重量的年周期变化来判定精子发生进程适用于蜥蜴类。[Objective] To study the male reproductive cycle of Leiolepis reevesii.[Method] 5~6 adult males of L.reevesii were collected every month.Their reproductive organ was dissected and observed.[Result] Annual variation was reflected in structure of reproductive organ of L.reevesii.Reduced rapidly from the maximum value in late June,the weight of testicular and the diameter of seminiferous tubules reached their smallest value in August,and then increased steadily from September to next year.The same change to epididymis and deferens occurred.Spermatogenesis also changed periodically with annual variation in reproductive organ.[Conclusion]Annual variation in weight of reproductive organ could be used in judging of spermatogenesis in Lizards class.
